When you break a workflow like that you not only drive people nuts but waste hours of their time with unbillable hours. Adding features is ok. I can elect to use them or not. But changing fundamental behaviors that have been in place for decades is just sadistic.

I've been using Alienware 25 AW2518Hf gaming monitor and it is one of the https://monitormega.com/best-monitor-for-fighting-games/ best fighting games monitors. One of my friends suggested me this monitor to me, it's been a year now I'm using this monitor and I regret nothing. If you want to go with this I'm 100% sure you will not regret it.

I am using Adobe Illustrator for over 10 years and this is such a flaw. I mean I can get used to it, but if another program as Affinity Designer has guides, I will switch soon to that program. Please fix this! Guides are no where to be found while moving paths, shapes etc. this is not good.

I'm surprised there are not more votes on this! please fix

THIS PROBLEM IS DRIVING ME CRAZY.

In order to be able to see my guides as I move them, I must have Real-Time Drawing and Editing off. Surely, this can be fixed so we can take advantage of this feature but still be able to see where we are moving our guides.

@George Williamson, telling people to "get better hardware" is not the solution. That's utterly ridiculous! I have a tower PC with three Nvidia 2080Ti's and the problem affects me just as much as anyone else.

Neither is the solution to "uncheck the Realtime drawing". This is a 'hack' that many people have suggested but fail to realize that in doing so they are disabling a feature that they are paying for. The reason we pay (pricey) subscriptions is to fund the continuous development and improvements. Switching new features off just to save one of the oldest and most fundamental features (guides) is ridiculous.

The Solution that we all need to PUSH adobe in to action is.... "fix the buggy software" !!

Well if it worked before they broke it, "average hardware" seems a bad argument to me. For example my iMac 2019 should be powerful enough to handle this (but I have this bug, too - also on other computers). It is just one of many bugs in Illustrator and if it does not appear on your machine, you are lucky. But don’t tell people to buy new hardware, because Adobe broke their software....

You can Solve it by Doing the following steps:
Go to Illustrator Preferences > Performance and un-check "Real-Time Drawing and Editing."
This happens because of average hardware. Get a better laptop I would say.

And today we've reached the v.25.2.2 and still haven't a fix for this bug!!!
Is it a joke?? The only solution at the moment is disable the real time preview but is a pain...

I vote for a better fix to this, meantime however, there is another useful work around here:
https://dviz.me/guides-disappear-1c688
Especially useful for me is this little trick found way down in that post: place guides on a separate layer, and turn off "preview" for that layer.

I hate this! Why would anyone want their guides to disappear when repositioning them?? Big thanks to Anonymous for sharing how to turn this off. Very dumb.

Guides disappear when I drag them to reposition. They work fine when I drag one out from the ruler, but if I try to reposition, they are not visible when I drag and they appear when I release.

Unchecking Real-Time Drawing is just a poor workaround and not a fix! Adobe introduced even more GPU related Bugs with Illustrator 2021! Come on Adobe, don’t think of adding useless new features - FIX the existing ones, that we need to use every day!

Problem solved!
Go to Illustrator Preferences > Performance and un-check "Real-Time Drawing and Editing."
See attachement.

Same issue here. Disabling GPU seems to solve. Is there a list of specific GPUs that seem to play nicer with Adobe going into future releases?

Known bug.

As a temp solution, disable GPU preview.

Please merge.

Dear ADOBE. Ive seen several comments from readers offering a solution by switching to CPU and disabling real-time drawing. And some of them even have responses from Adobe asking users to try the same thing. THESE ARE HACKS !! This is unacceptable. You are all like "YAY we've developed Real-time drawing with GPU to make your lives better" but when your customers discover that it screws up a fundamental basic such as guides, the solution appears to be NOT to use the new features !!

You have been 'refining this product since 1989, and you are a multi million dollar giant with huge teams of well paid developers. Just fix the guides !!!!
